Definitions
- the present invention relates to a method of manufacturing an aircraft stopper made at least partially of composite material.
- the present invention also relates to an aircraft stopper made at least partially of carbon composite material.
- the aircraft doors are constituted by a structure adapted to receive mechanisms for performing opening and closing maneuvers.
- the structure of the door is articulated around a room called “door arm” which is itself attached to the structure of the fuselage.
- the support of the door on the fuselage consists of a discontinuous system and is made through parts called “stops” and fixed on the one hand on the door and, on the other hand, vis-à-vis on the fuselage.
- the door stops are made of aluminum alloys or titanium alloys.
- An object of the invention is to provide an aircraft stop that combines the good performance of metal materials with the lightness of the composite material.
- the method according to the present invention provides a solution to all these problems.
- the invention relates to an aircraft stopper manufacturing method comprising a metal insert by molding a composite material of resin and carbon fibers, comprising at least one step of draping a stack of parts made by means of a superposition of pre-impregnated carbon sheets, the layers being oriented so as to ensure maximum cohesion of the assembly around the metal insert.
- the method can comprise the following steps:
- a piece is made by flat layering of several layers of pre-impregnated resin-coated carbon sheets, this draping comprising a set of layers positioned longitudinally and layers separating laterally in two parts separated by a median portion (step 1), - then said middle portion is wound around a metal insert provided with two shoulders (step 2),
- the invention also relates to an aircraft stop comprising a metal insert manufactured by implementing a manufacturing method according to the invention.
- FIG. 1 schematically shows a top view of an aircraft door stop.
- FIG. 2 schematically shows a perspective view of the stop of Figure 1, the stop screw having been removed.
- FIG. 3 schematically represents a view of the lay-up of carbon sheets in a two-part part corresponding to step 1 of a manufacturing method according to the invention.
- FIG. 4 schematically shows a view illustrating step 2 of a manufacturing method according to the invention.
- FIG. 5 schematically shows a view illustrating the beginning of step 3 of a manufacturing method according to the invention.
- FIG. 6 schematically represents a view illustrating the end of step 3 of a manufacturing method according to the invention
- FIG. 7 schematically represents a view illustrating step 4 of a manufacturing method according to the invention
- FIG. 8 schematically represents a view illustrating step 5 of a manufacturing method according to the invention
- FIG. 9 schematically represents a view illustrating the beginning of step 6 of a manufacturing method according to the invention
- FIG. 10 schematically represents a view illustrating the end of step 6 of a manufacturing method according to the invention
- FIGS. 1 and 2 show an aircraft door stop which comprises a base 1 provided with an angle bracket 2 carrying an abutment screw 3.
- the stop screw 3 has been removed in FIG. appear a metal ring 4.
- the abutment being made of composite material, it is not possible, given the importance of efforts to cash, to screw the abutment screw in a plastic material: it is therefore necessary to set up a metal insert, by example a metal ring 4.
- this metal ring 4 is very firmly anchored in the mass of the stem 2.
- this ring 4 has the shape of an insert provided with at least two shoulders: one at each end.
- Figure 3 represents the first step of the implementation of the method.
- a sheet 10 having the shape shown in FIG. 3 having a rectilinear portion 11 and two lateral flaps 13 and 14 separated by a medial portion 12 is made flat by layering of several layers of carbon sheets.
- carbon are arranged rectilinearly in the mass of the rectilinear portion 11 of the piece 10, and oriented obliquely in the lateral flaps 13, 14, 15, 16.
- the length of the middle portion 12 of the rectilinear portion 11 is equal at the distance separating the two shoulders of the insert 4.
- the part 10 is made by draping a first part comprising the parts represented by radiating segments and a second larger surface part whose contour corresponds to the outer contour of the part 10.
- the carbon sheets are made by superposing folds about 12mm wide oriented at the angles shown in Figure 3.
- Figure 4 shows the next step of the implementation of the method (step 2).
- the median portion 12 of the rectilinear portion 11 of the piece 10 made by draping pre-impregnated resin-coated carbon sheets is placed in the groove formed between the two shoulders of the insert 4.
- the part 10 is bent and formed around the metal insert 4, in a V-shaped.
- the side flaps 13 and 14 are intended to be folded over one another, while the flaps before 15 and 16 are intended to be folded under the metal ring 4 to form a lower support surrounding the portion of the metal ring 4 diametrically opposite the middle portion 12.
- a stack in the form of strips of lengths between 150 and 215 mm is necessary.
- Figure 5 shows the third step after the folding of the side flaps 13 to 16, in the draped conformation allowing the introduction into a cooking tool.
- the folding of the tips or flaps 13 and 14 on one another ensures the cohesion of the rear part, while the folding parts 15 and 16 under the metal insert 4 provides maximum cohesion of the set including the metal insert 4.
- FIG. 7 represents the fourth stage of implementation of a method according to the invention, into which is inserted from below and fixed in place a reinforcement piece intended to be oriented along the longitudinal median plane of the assembly. shown in Figure 6.
- FIG. 8 represents the fifth stage of implementation of a method according to the invention, in which is inserted from below and fixed in place a base plate 30 intended to be oriented substantially horizontally in order to seal the lower part. from the whole. The ends of the rectilinear portion 11 of the piece 10 are then folded under the sole 30 to surround the whole assembly.
- Figures 9 and 10 illustrate the sixth step of a method according to the invention corresponding to the successive establishment of parts 40, 50, 60 which constitute the sole of the abutment.
- a door stop having excellent qualities of mechanical strength, fatigue resistance is obtained, while being much lighter than a metal stop, which is very interesting given the number of stops placed on an aircraft.
